ABSTRACT:
A load responsive flow control valve for use in a system controlling a plurality of loads. The system is powered by a single fixed displacement pump equipped with a load responsive bypass valve or a variable displacement pump equipped with load responsive control, which during simultaneous control of multiple loads automatically maintains the pump discharge pressure at a level higher by a constant pressure differential than the pressure required by the largest load being controlled. The load responsive valve is of a four position float type which in the float position while isolating system pump and connecting both of the load chambers to system reservoir blocks pressure sensing ports from inlet chamber and connects them to system reservoir to permit full unloading of the system pump.
